Feedback design for multi-transmission reception point transmission

[0064]The described techniques relate to improved methods, systems, devices, or devices that support feedback designs transmitted by multi-transmit receiving points (multi TRP). Generally, the described techniques provide coordinated communication between the transmitting reception point (TRP) set and the user equipment (UE), so that the UE can be configured to be configured to operate in one of the coordinated transmission modes in which the downlink control signaling and the UE are configured. To identify configurations for transmitting feedback to at least one of the TRP.

[0065]In an example, the first TRP in the TRP set can send a configuration message for configuring the UE uses a first coordinated transmission mode in different coordinated transmission mode sets and TRP set communication. Each coordinated transmission mode can indicate a number of uplink and downlink control channels and several uplink and downlink data channels, which are configured for communication between specific TRP and UEs. The first TRP can transmit a downlink control information (DCI) based on the configuration message, which includes at least one indicator and resource license for a downlink coordinated transmission from one of the TRPs to the UE.

[0066]In some cases, the DCI may include a downlink assignment index (DAI) indicator, acknowledgment (ACK), or negative confirmation (NACK) (eg, an ACK / NACK) resource indicator (ARI), and a feedback gap indicator (eg, , K1 value), the feedback gap indicator corresponds to a corresponding physical UNDP control channel (PUCCH) message corresponding to the physical downlink shared channel (PDSCH) message and when the UE is expected to send the feedback PDSCH message Time gap. Based on the combination of DAI, ARI, and feedback gap indicators, the UE can determine a feedback configuration for transmitting a feedback message (for example, hybrid automatic retransmission request (HARQ), such as a HARQ-ACK or HARQ-NACK message) within the PUCCH message. . The feedback configuration can indicate the number of ACK / NACK bits in the feedback message, which is the number of PUCCH resources allocated by the report ACK / NACK feedback, and the number of TRPs, which TRPs to send feedback messages, or any combination thereof.

[0067]The UE can monitor the resources indicated in the license and receive coordinated transmission according to the configuration of the sending mode communication. The UE can determine if it can successfully decode coordinated transmission, and can transmit a feedback message to the coordinated transmission according to a feedback configuration corresponding to at least one indicator and the first coordination transmission mode. According to some aspects, the UE can determine the feedback configuration without the need for TRP to undertake additional signaling overhead to the UE clearly indicates the feedback configuration.

[0068]The specific aspects of the subject matter described herein can be implemented to implement one or more advantages. The techniques described can support improvements in the ACK / NACK feedback frame, reduce signaling overhead, and improve reliability, and the like. Therefore, supported techniques can include improved network operations, and in some examples, network efficiency, and the like can be promoted.

[0069]All aspects of the present disclosure are first described in the context of a wireless communication system. Then, aspects of the quasi-co-amp (QCL) association configuration and process flow are described. The various aspects of the present disclosure are further shown and described with reference to the device diagram, system diagram, and flowchart relating to the feedback design sent by the multi TRP.

[0070]figure 1 An example of a radio communication system 100 that supports a multi-TRP transmission according to various aspects of the present disclosure is shown. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 can be a long-term evolution (LTE) network, a high-level LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some cases, the wireless communication system 100 can support enhanced broadband communication, super reliable (e.g., task key) communication, low delay communication, or communication with low cost and low complex devices.

[0071]The base station 105 can wirelessly communicate with the UE 115 via one or more base station antennas. The TRP 105 can be an example of a base station 105. The base station 105 described herein can include or can be referred to by those skilled in the art as a base station transceiver station, a radio base station, an access point, a wireless transceiver, NodeB, ENODEB (eNB), the next generation Node B or Gigabit Station (GIGA- NodeB) (any of these can be referred to as GNB), home nodeb, home eNodeb, or some other suitable terms. Wireless communication system 100 can include different types of base station 105 (eg, a macro base station or small cell base station). The UE 115 described herein can be capable of communicating with various types 105 and network devices, including macro eNB, small cells eNB, GNB, relay base stations, and the like.

[0072]Each base station 105 can be associated with a particular geographic coverage area 110, in which communication with various UE 115 is supported. Each base station 105 can provide communication coverage to the respective geographic coverage area 110 via communication link 125, and communication link 125 between base stations 105 and UE 115 can utilize one or more carriers. The communication link 125 shown in the wireless communication system 100 can include an uplink transmitted from the UE 115 to the base station 105, or from the base station 105 to the downlink transmission of the UE 115. The downlink transmission can also be referred to as a forward link transmission, while the uplink transmission can also be referred to as a reverse link transmission.

[0073]The geographic coverage area 110 of the base station 105 can be divided into a sector constituting a portion of the geographic coverage area 110, and each sector can be associated with a cell. For example, each base station 105 can provide communication coverage for macro cells, small cells, hotspots, or other types of cells or various combinations thereof. In some examples, the base station 105 can be movable, so that the communication coverage can be provided for the moving geographic coverage area 110. In some examples, different geographic coverage area 110 associated with different techniques can overlap, and overlapping geographic coverage area 110 associated with different techniques may be supported by the same base station 105 or different base station 105. For example, the wireless communication system 100 can include a heterogeneous LTE / LTE-A / LTE-A PRO or NR network, where different types of base station 105 provide overlay for different geographic coverage area 110.

[0074]The term "cell" refers to a logical communication entity (e.g., by carrier) for communication with the base station 105, and may be identifier (for example, physical cell identifier) ​​for distinguishing adjacent cells for distinguishing between the same or different carriers. (PCID), the Virtual Community Identifier (VCID)) is associated. In some examples, the carrier can support multiple cells, and different cells can be based on different protocol types (eg, machine type communication (MTC), narrowband net (NB-IOT), enhanced mobile broadband (EMBB) or other ) To configure, these protocol types can provide access for different types of devices. In some cases, the term "cell" can refer to a portion of the geographic coverage area 110 operated thereon (eg, a sector).

[0075]The UE 115 can be dispersed throughout the wireless communication system 100, and each UE may be fixed or moving. UE 115 can also be referred to as mobile devices, wireless devices, remote devices, handheld devices, or user equipment, or some other suitable terms, which may also be referred to as cells, stations, terminals, or clients. UE 115 can also be personal electronic devices such as cellular phones, personal digital assistants (PDAs), tablets, laptops, or personal computers. In some examples, the UE 115 can also refer to a wireless local loop (WLL) station, an Internet of Things (IOT) device, a network (IOE) device or MTC device or a similar device, which can be implemented in various items, For example, home appliances, vehicles, meters, or similar devices.

[0076]Some UEs 115, such as MTC or IOT devices, can be low cost or low complexity devices, and automatic communication between machines (eg, communication via machine (M2M)). M2M communication or MTC can refer to data communication technologies that allow the device to communicate with each other or base station 105 without manual intervention. In some examples, the M2M communication or MTC may include communication from the device, which integrate sensors or meters to measure or capture information, and relays the information to a central server or application, the central server or application can take advantage of this Information or presenting this information to humans with the program or application interaction. Some UE 115 can be designed to collect information or enable automation behavior of the machine. Application examples of MTC devices include intelligent metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensation, physical access control and transaction-based Business charges.

[0077]Some UE 115 can be configured to use an operation mode such as a half-duplex communication (e.g., supporting one-way communication via transmission or reception), but different transmission and reception mode). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power savings techniques of the UE 115 include "deep sleep" modes that are not involved in the active communication, or operate on a limited bandwidth (eg, according to narrowband communication). In some cases, the UE 115 can be designed to support critical functions (eg, task key functions), and wireless communication system 100 can be configured to provide super-reliable communication to these functions.

[0078]In some cases, the UE 115 can also be able to communicate with other UE 115 (eg, using point-to-point (P2P) or device devices (D2D) protocols). One or more UEs in the group of the UE 115 of D2D can be within the geographic coverage area 110 of the base station 105. Other UEs 115 in this group can be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmission from the base station 105. In some cases, the group of UE 115 communicating via D2D communication can utilize a pair of (1: m) systems, where each UE 115 is transmitted to each other UE 115 in the group. In some cases, base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication is performed between the UE 115 without the participation of the base station 105.

[0079]The base station 105 can communicate with the core network 130 and to each other. For example, base station 105 can be coupled to core network 130 by backhaul link 132 (e.g., via S1, N2, N3, or other interface). The base station 105 can communicate with each other by a return link 134 (e.g., between the base station 105) or indirectly (e.g., via core network 130) or indirectly (e.g., via X2, XN or other interface).

[0080]Core Network 130 can provide user authentication, access license, tracking, Internet protocol (IP) connection, and other access, route, or mobility. The core network 130 can be an evolved packet core (EPC), which can include at least one mobility management entity (MME), at least one service gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW) . MME can manage non-access layers (e.g., control surface) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with EPC. The user IP packet can be sent via the S-GW, and the S-GW itself can be connected to the P-GW. P-GW can provide IP address allocation and other functions. P-GW can be connected to the network operator's IP service. Operators' IP services can include access to the Internet, intranet, IP Multimedia Subsystem (IMS) or Packet Exchange (PS) stream.

[0081]At least some network devices, such as base station 105, may include subassemblies, such as access network entities, which may be an example of an access node controller (ANC). Each access network entity can communicate with the UE 115 via several other access networks, which can be referred to as radios, smart radios, or TRPs. In some configurations, each of the various functions of each access network entity or base station 105 can be distributed across various network devices (eg, radio heads and access network controllers), or merged into a single network device (eg, base station 105) in.

[0082]Wireless communication system 100 can operate using one or more bands, typically within 300 MHz to 300GHz. Generally, the area of ​​300 MHz to 3GHz is known as a special high frequency (UHF) region or a germplatte, because the wavelength is about one minute and one meter. UHF waves may be blocked or changed by buildings and environmental features. However, for the macro cell, the wave can be fully penetrating the structure to provide a service to the UE 115 located in the room. The transmission of the UHF wave can be transmitted to a smaller antenna and a shorter range than the smaller frequency (HF) or very high frequency (VHF) portion of the spectrum of 300 MHz or less, the transmission of the UHF wave can be in a smaller antenna and a shorter range (eg, less than 100 km) is associated.

[0083]The wireless communication system 100 can also operate in an ultra-high frequency (SHF) region using 3GHz to 30 GHz, which is also referred to as a cm belt. The SHF region includes a belt such as a 5GHz industry, a scientific and medical (ISM), which can be used by an apparatus that can tolerate an interference from other users.

[0084]The wireless communication system 100 can also operate in the extremely high frequency (ehf) region of the spectrum (e.g., from 30 GHz to 300 GHz), which is also referred to as a millimeter band. In some examples, the wireless communication system 100 can support millimeter wave (MMW) communication between the UE 115 and the base station 105, and the EHF antenna of the corresponding device can be smaller and closer to the UHF antenna. In some cases, this can facilitate the use of antenna array within the UE 115. However, compared to SHF or UHF, the propagation transmitted by the EHF may be limited to even larger atmospheric attenuation and shorter range. The techniques disclosed herein can be employed across one or more different frequency regions, and the specified use of the belts across these frequency regions can be different due to national or regulatory mechanisms.

[0085]In some cases, the wireless communication system 100 can utilize both licensed and unauthorized radio spectrum tapes. For example, wireless communication system 100 can use license auxiliary access (LAA), LTE-unlike (LTE-U) radio access technology or NR technology such as a 5 GHz ISM belt. When operating in an unlicenated radio spectrum tape, wireless devices such as base station 105 and UE 115 can be used first-listening (LBT) program to ensure that the frequency channel is clear before transmitting data. In some cases, the operation in the unlike band can be combined based on the carrier aggregation configuration, in conjunction with component carriers (CC) operating in the license tape (for example, LAA). The operation in the unus of spectrum can include a downlink transmission, an uplink transmission, a point-to-point transmission, or a combination of these. The duplex in the unlike spectrum can be based on the frequency division duplex (FDD), a time division duplex (TDD), or a combination of both.

[0086]In some examples, base station 105 or UE 115 can be equipped with a plurality of antennas, which can be used to employ techniques such as transmit diversity, reception diversity, multi-input multi-output (MIMO) or beamforming. For example, the wireless communication system 100 can use a transmission scheme between the transmitting device (e.g., base station 105) and the receiving device (e.g., UE 115), wherein the transmitting device is equipped with multiple antennas, and the receiving device is equipped with one or more roots. antenna. MIMO communication can transmit or receive multiple signals via a different spatial layer to increase spectral efficiency, which can be referred to as space multiplexing. For example, a plurality of signals can be transmitted by a transmitting device via a different antenna or a different antenna combination. Also, a plurality of signals may be received by a receiving device via a different antenna or a different antenna combination. Each of the plurality of signals may be referred to as a separate space stream, and can carry bits associated with the same data stream (eg, the same codeword) or different data streams. Different spatial layers can be associated with different antenna ports for channel measurements and reports. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0087]Brass forming, which may also be referred to as spatial filtering, oriented or oriented, is a spatial path that can be used at a transmission device or receiving device (e.g., base station 105 or UE 115) to shape between the transmission device and the receiving device or Signal processing techniques for guiding antenna beam (eg, transmitting beams or receiving beams). The beamforming can be achieved by combining signals transmitted via an antenna element of the antenna array such that signals propagating in a particular direction relative to an antenna array have undergone phase long interference and other signals have undergone disintegration. Adjustment of signals transmitted via antenna element may include a transmitting device or a receiving device to apply a certain amplitude and phase shift to signals carried by each of the antenna elements associated with the device. Adjustments associated with each of the antenna elements can be defined by beam-shaped weights associated with a particular direction (e.g., an antenna array relative to the transmitting device or receiving device, or relative to some other direction).

[0088]In one example, the base station 105 can perform beamforming operations to communicate with the UE 115 using a plurality of antenna or antenna array to communicate with the UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times in different directions in different directions, which can include different beam molding weights associated with different transmission directions. Send signal. The transmission in different beam directions can be used (e.g., by base station 105 or receiving devices, such as UE 115), is identified by the base station 105, which is subsequently transmitted and / or received by the base station 105. Some signals, such as data signals associated with a particular receiving device, can be transmitted by the base station 105 in a single beam direction (e.g., in a direction associated with the receiving device (such as UE 115)). In some examples, the beam direction associated with the transmission along the single beam direction can be determined at least in part on signals transmitted in different beam directions. For example, the UE 115 can receive one or more of the signals transmitted by the base station 105 in different directions, and the UE 115 can report the indication of the signal that has the highest signal quality or other acceptable signal quality thereof to the base station 105. . Although these techniques are described with reference to the signals transmitted by the base station 105 in one or more directions, the UE 115 can transmit a signal in different directions in different directions (for example, for identification by the UE 115). The beam direction of the transmitted or received), or transmits a signal in a single direction (e.g., to send data to the receiving device).

[0089]The receiving device (eg, UE 115 may be an example of a MMW receiving device), attempts, multiple reception beams when receiving various signals from base station 105 (such as synchronization signals, reference signals, beam selection signals, or other control signals). . For example, the receiving apparatus can attempt to attempt to attempt in the following manner: reception via a different antenna sub-array, by processing the received signal according to different antenna array, by receiving the plurality of antenna elements applied to an array of antenna arrays Different receiving beamforming weights of the signals are received, or by processing the received signals by different receiving beam molding weights applied to signals applied to multiple antenna elements applied at the antenna array, any of them can be referred to as Different receiving beams or reception directions "listen". In some examples, the receiving device can use a single receiving beam to receive along a single beam direction (eg, when receiving the data signal). The single receiving beam can be based at least in part on the beam direction determined by the listening of the received beam direction (eg, based on at least partially based on the listening in the plurality of beam directions, to have the highest signal strength, the highest signal-to-noise ratio or other Aligned on the beam direction of the acceptable signal quality).

[0090]In some cases, the antenna of the base station 105 or UE 115 may be located within one or more antenna arrays, which can support MIMO operation, or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays can be co-located at an antenna combination device, such as at the antenna tower. In some cases, an antenna or antenna array associated with base station 105 can be located in a different geographic location. The base station 105 can have an antenna array with a plurality of rows and columns, and base station 105 can be used to support beamforming of communication with the UE 115. Also, the UE 115 can have one or more antenna arrays that can support various MIMO or beamforming operations.

[0091]In some cases, the wireless communication system 100 can be a packet-based network, which is run according to the hierarchical stack. In the user plane, the communication at the bearer or packet data aggregation protocol (PDCP) layer can be based on IP. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly in some cases to communicate on a logical channel. The Medium Access Control (MAC) layer can perform priority processing and multiplexing logical channels into a send channel. The MAC layer can also use HARQ to provide retransmission in the MAC layer to improve link efficiency. On the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of the RRC connection between the UE 115 and the base station 105 or the core network 130 to support the radio carrying of user plane data. At the physical layer, the transmission channel can be mapped to the physical channel.

[0092]In some cases, the UE 115 and the base station 105 can support data retransmission to increase the possibility of successful receiving data. HARQ feedback is a technique that increases the possibility of receiving data through communication link 125. The HARQ can include an error detection (eg, using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (eg, auto-retransmission request (ARQ)). HARQ can improve throughput at the MAC layer under harsh radio conditions (eg, signal-to-noise specific conditions). In some cases, the wireless device can support the same time slot HARQ feedback, where the device can provide HARQ feedback to data received in the previous symbol in the time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or in some other time intervals.

[0093]The time interval in the LTE or NR can be represented by a multiplication of the basic time unit, for example, which can refer to the sampling period of Ts = 1/30, 720,000 seconds. The time interval of the communication resource can be organized according to a radio frame having a duration of 10 milliseconds (MS), wherein the frame cycle may be represented as TF = 307, 200Ts. The radio frame can be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame may include 10 subframe numbered 0 to 9, and each subframe may have a duration of 1 millisecond. The subframe may be further divided into two time slots, each time slot has a duration of 0.5 milliseconds, and each time slot can include 6 or 7 modulation symbol cycles (eg, depending on the cycle of each symbolic cycle. The length of the prefix). No cyclic prefix, each symbol period can contain 2048 sampling cycles. In some cases, the subframe may be the minimum scheduling unit of the wireless communication system 100, and may be referred to as a transmission time interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 may be shorter than the subframe, or can dynamically select (eg, in a burst of the shortened TTI (STTI), or in selected component carriers using STTI ).

[0094]In some wireless communication system 100, the time slot can be further divided into a plurality of microat slots comprising one or more symbols. In some examples, the symbol of the microelax or microext can be the minimum scheduling unit. For example, the duration of each symbol can vary depending on the subcarrier interval or operating frequency band. Further, some wireless communication systems can perform slot aggregation, wherein the plurality of time slots are polymerized together and used for communication between the UE 115 and the base station 105.

[0095]The term "carrier" refers to a radio spectrum resource set having a defined physical layer structure for supporting communication on communication link 125. For example, the carrier of the communication link 125 may include a portion of the radio spectrum band operated in accordance with a physical layer channel of a given radio access technology. Each physical layer channel can carry user data, control information, or other signaling. The carrier can be associated with a predefined frequency channel (eg, E-UTRA absolute radio frequency channel number (EARFCN)), and can be positioned according to the channel grid so as to be discovered by the UE 115. The carrier may be a downlink or an uplink (eg, in the FDD mode), or configured to carry downlink and uplink communication (eg, in TDD mode). In some examples, the signal waveform transmitted by the carrier can be composed of a plurality of subcarriers (e.g., using a multi-carrier modulation (MCM) technology, such as discrete Fourier transform expansion orthogonal frequency division multiplexing (DFT-S-OFDM)) .

[0096]For different radio access technologies (eg, LTE, LTE-A, LTE-A Pro, NR), the organizational structure of the carrier can be different. For example, communication on the carrier can be organized according to TTI or Timetry, each TTI or slot may include user data and support control information or signaling for decoding user data. The carrier can also include dedicated acquisition signaling (eg, synchronization signals, or system information) and control signaling operations for carrier coordination operations. In some examples (eg, in the carrier aggregation configuration), the carrier may have an acquisition signaling or control signaling for other carrier coordination operations.

[0097]Physical channels can be multiplexed on the carrier according to various techniques. Physical control channels and physical data channels can be multiplexed on the downlink carrier, for example, by using time division multiplexing (TDM) technology, frequency division multiplexing (FDM) technology or hybrid TDM-FDM technology. In some examples, the control information transmitted in the physical control channel can be distributed between different control regions in a cascaded manner (e.g., in a common control area or a common search space and one or more UE specific control zones or UEs. A specific search space between.

[0098]The carrier can be associated with a specific bandwidth of the radio spectrum, in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several predetermined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40 or 80 MHz) of a carrier of a particular radio access technology. In some examples, each of the served UEs 115 can be configured to operate on a portion or all of the carrier bandwidth. In other examples, some UE 115 can be configured to operate (eg, narrowband protocol type "band using a narrowband protocol type associated with a predefined portion or range (e.g., subcarrier wave set or RB set). "deploy).

[0099]In a system using MCM technology, the resource element can consist of a symbolic period (eg, a modulation symbol duration) and a subcarrier, wherein the symbol period and the subcarrier spacing are inverse comparison. The number of bits carried by each resource element may depend on the modulation scheme (eg, the order of the modulation scheme). Therefore, the more resource elements received by the UE 115, the higher the order of the modulation scheme, the higher the data rate of the UE 115. In the MIMO system, wireless communication resources may refer to a combination of radio spectrum resources, time resources, and spatial resources (e.g., space layers), and use multiple spatial layers to further increase the data rate communicating with the UE 115.

[0100]The device (e.g., base station 105 or UE 115) of the wireless communication system 100 may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configurable to support a communication over one of the carrier bandwidth. In some examples, the wireless communication system 100 can include base stations 105 and / or uES 115 that can support while communicating via carriers associated with more than one different carrier bandwidth.

[0101]The wireless communication system 100 can support communication with the UE 115 in multiple cells or carriers, which can be referred to as carrier aggregation or multi-carrier operations. Depending on the carrier aggregation configuration, the UE 115 can be configured with a plurality of downlink CCs and one or more uplink CCs. Carrier aggregation can use both FDD and TDD components.

[0102]In some cases, wireless communication system 100 can utilize enhanced CC (ECC). The ECC can be characterized by one or more features, including: a wider carrier or frequency channel bandwidth, shorter symbol duration, shorter TTI duration, or modified control channel configuration. In some cases, the ECC can be associated with a carrier aggregation configuration or a dual connection configuration (e.g., when multiple service cells have a secondary or unimagical return link). The ECC can also be configured to use in a spectrum or shared spectrum (for example, in which more than one operator is allowed to use spectrum). The ECC with a wide carrier bandwidth can include one or more bands, which may be utilized by UE 115 that cannot be monitored to the entire carrier bandwidth or otherwise configured to use a limited carrier bandwidth (e.g., saving power).

[0103]In some cases, the ECC can utilize a symbol duration than other CCs, which may include the use of a decreased symbol duration using a symbol duration of other CCs. A shorter symbol duration can be associated with an interval between the adjacent subcarriers. With ECC's equipment, such as UE115 or base station 105, a wideband signal can be transmitted in a reduced symbol duration (eg, 16.67 microseconds) (e.g., according to 20, 40, 60, 80 MHz frequency channel or carrier bandwidth). The TTI in the ECC can consist of one or more symbolic cycles. In some cases, the TTI duration (ie, the number of symbols in TTI) may be variable.

[0104]Wireless communication systems such as NR systems, any combination that can be utilized by licenses, sharing, and non-license bands. The flexibility of the ECC symbol duration and subcarrier spacing can allow the use of ECC across multiple spectrum. In some examples, NR shared spectrum can increase spectral utilization and spectral efficiency, specifically, through dynamic vertical (e.g., cross-frequency domain) and levels of resource shared.

[0105]The first TRP (e.g., base station 105) in the TRP set can send a configuration message for configuring the UE uses a first coordinated transmission mode in different coordinated transmission mode sets and TRP set communication. Each coordinated transmission mode can indicate a number of uplink and downlink control channels and several uplink and downlink data channels, which are configured for communication between specific TRP and UE 115. The first TRP can transmit the DCI based on the configuration message, and the DCI includes at least one indicator and resource license for one of the downlink coordinated by one of the TRPs to the UE.

[0106]In some cases, the DCI may include a DAI indicator, an ARI, and a feedback gap indicator (eg, K1 value). Based on the combination of DAI, ARI, and feedback gap indicators, the UE 115 can determine a feedback configuration for transmitting a feedback message (e.g., HARQ-ACK message) within the PUCCH message. The feedback configuration can indicate the number of ACK / NACK bits in the feedback message, the number of PUCCH resources assigned by the report ACK / NACK feedback, the number of TRPs, which TRPs are to send feedback messages to which TRPs. The UE 115 can monitor the resources indicated in the license and receive coordinated transmission based on the configuration of the send mode. The UE 115 can determine if it can successfully decode coordinated transmission, and may transmit a feedback message for coordinated transmission according to a feedback configuration corresponding to at least one indicator and the first coordination transmission mode.

[0107]figure 2 An example of a wireless communication system 200 that supports a multi-TRP transmitted in accordance with various aspects of the present disclosure. In some examples, the wireless communication system 200 can implement all aspects of the wireless communication system 100.

[0108]In the wireless communication system 200, multiple TRP 105, which can befigure 1 An example of a base station 105 can be configured to communicate with a single UE 115 (such as UE 115-A). The TRP 105 can communicate with the UE 115-A in a non-coherent manner (e.g., according to the non-coherent federated transmission (NCJT)). TRP 105 and UE 115-A can establish a downlink connection 205 (for example, downlink connection 205-A and TRP 105-B of the TRP 105-B) and uplink connection 210 (eg, , The uplink connection 210-A and TRP 105-B of the TRP 105-A are communicating. Each TRP 105 can be capable of transmitting a downlink message (e.g., physical downlink control channel (PDCCH), and PDSCH messages) on the corresponding downlink connection 205, and the UE 115-A can be A uplink message (e.g., a PUCCH message or a physical Upline Shared Channel (PUSCH) message is sent on the corresponding uplink connection 210). TRP 105-A and TRP 105-B can be each as an example of base station 105 as described herein.

[0109]TRP 105-A and 105-B can communicate with the UE 115-A according to the transmission mode coordinated between TRP 105. The transmission mode can refer to a specific configuration of NCJT wireless communication between the UEs 115-A and TRP 105. The transmission mode can relate to the content or repeated configuration of the PDCCH resource or PDSCH resource that communicates with the UE 115-A, and the content or repetition of the PDCCH and PDSCH messages. For example, according to the first transmit mode, TRP 105-A and TRP 105-B can collect a PDCCH message and a PDSCH message. In another send mode, TRP 105-A and TRP 105-B can jointly send a PDSCH message and two PDCCH messages, where the PDCCH message is a copy. inFigures 3A to 5 An example of a transmission mode is shown and described.

[0110]TRP 105 and UEs 115-A can communicate with each other to coordinate the transmission mode. For example, TRP 105 can send a configuration message indicating which transmission mode is being used. In some cases, the configuration message can be sent as part of the RRC signaling. In some other examples, the UE 115-A can implicitly determine which transmission mode is being used. In some cases, implicit determination can be made based on the reference signal or the information included in the DCI. For example, when a PDSCH resource is configured, TRP 105 can indicate the number of defined numbers (eg, maximum) of each PDSCH. The definition number of codewords that identify each PDSCH can assist UE 115-a to determine multiple TRP send modes.

[0111]TRP 105-A and TRP 105-B can have ideal or near ideal connections (eg, backhaul links 134-a), so that TRP 105-A and TRP 105 are used when using return links 134-A. B The communication between B is zero delay or approaches zero delay in some examples, and the return links 134-A, TRP 105-A and TRP 105-B can be capable of lower loss levels (for example, nearly loss) Quick communication (for example, near-instantaneous). Thus, TRP 105 can be able to coordinate dynamic signaling via the return link 134-A, without having a significant overhead or an introduction of a significant delay.

[0112]Depending on the configured transmission mode, the UE 115-A can have multiple configurations for reporting the ACK / NACK feedback. In some cases, due to the ideal return links 134-A, the service TRP 105 can be able to communicate ACK / NACK feedback to other TRP 105 at minimally or without delay. In some cases, different feedback configurations may include allocating a different number of PUCCH resources for transmitting a PUCCH message including ACK / NACK feedback. In some cases, different feedback configurations can include different numbers of bits for conveying the ACK / NACK information. Some feedback configurations can send ACK / NACK feedback to only one TRP 105 (eg, TRP 105-A or TRP 105-B), where other feedback configurations can be sent back to two or more TRP 105 (For example, in broadcast transmission). Thus, due to the plurality of possible configurations of ACK / NACK feedback, the UE 115-A and TRP 105 can implement techniques to establish a framework for ACK / NACK feedback for different transmission modes. Based on the established framework, TRP 105 can be able to communicate parameters to the UE 115-A signal so that the UE 115-A can determine a feedback configuration for transmitting ACK / NACK feedback.

[0113]The TRP 105 can configure the UE 115-A using multiple control resource sets for each serving cell of each time slot. Each service cell can indicate the activity bandwidth (BWP) of the service cell, corresponding to frequency resources assigned to the cells of the UE 115-A, and the UE 115-A can monitor the PDCCH message in one or more PDCCH monitoring.

[0114]The UE 115-A can receive a PDCCH message on the downlink connection 205 during the PDCCH monitoring timing, and select the ACK / NACK feedback option based on the indication included in the DCI included in the PDCCH message. For example, the UE 115-A may determine a feedback configuration based on the DAI, ARI, and the feedback gap indicator (e.g., the K1 value or PDSCH to the HARQ timing indicator), the feedback gap indicator and the PDSCH message and the corresponding ACK / NACK feedback The gap is related. Based on the combination of DAI, ARI, and K1, the UE115-A can determine the number of HARQ ACK / NACK information bits and / or the number of PUCCH to be used / or the number of PUCCH to be used during reporting ACK / NACK feedback. The TRP 105 can communicate with the DAI / ARI / K1 instructions by backharable link 134-A communication.

[0115]In some cases, TRPS 105 can indicate the number of defined numbers (e.g., maximum) per PDSCH, and the defined number of codewords per pdsch may correspond to the number of ACK / NACK bits to be used by the UE 115-A. In some cases, the definition number indicating the codeword can assist the UE 115-A distinguishable different transmission mode (eg, as shown in Figure 3).Figure 6 The described above is described). In some examples, TRPS 105 can be configured with different transmission modes (e.g., by configuring the number of PDSCH and PDCCH resources) by RRC signaling (eg, by configuring the number of PDSCH and PDCCH resources).

[0116]UE 115-A can also follow the QCL configuration in the PUCCH resource configuration and the ARI in the DCI to determine the PUCCH message containing the ACK / NACK feedback to TRP 105-A or TRP 105-B, or whether to broadcast a PUCCH message to TRP Both 105-A and TRP 105-B. If the PUCCH message is sent only to a TRP 105, the UE 115-A can determine which TRP 105 transmitted to the PUCCH message. In some cases, the PUCCH resource can be configured to be QCL with the downlink reference signal based on the spatial domain parameter. If configured, the UE 115-A can transmit the PUCCH message using the same spatial domain filter as the reception of the downlink reference signal.

[0117]For example, if the PUCCH resource indicated by the ARI is a QCL associated with a downlink reference signal, the feedback configuration can indicate that the UE 115-A is to send a PUCCH message containing ACK / NACK feedback to a TRP 105. If the PUCCH resource is a QCL having different QCL assumptions associated with two different downlink reference signals, the feedback configuration can indicate that the UE 115-A is to send the PUCCH message to a plurality of TRP 105 (eg, send to the TRP 105) Each of -A and TRP 105-B).

[0118]In some cases, the UE 115-A may be configured with a plurality of scrambling identifiers (e.g., configurations, information such as HoppingID), where each scrambling identifier corresponds to one of a plurality of TRP 105. The scramble identifier can be used by the UE115-A to generate a sequence (eg, a low peak average power ratio (PAPR) sequence, or a pseudo-random sequence) for the PUCCH transmission (eg, a PUCCH transmitted by Carrying ACK / NACK feedback). The generated sequence can be used as a demodulated reference signal (DMRS) sequence for PUCCH transmission (eg, in format 1, 2, 3, and 4). Additionally or alternatively, the generated sequence can be used to modulate the payload of the PUCCH (e.g., in format 0). For the PUCCH transmitted from one or more UEs 115 to TRP 105-A and 105-B, interference between the UE 115 and TRP 105 can be reduced by different PUCCH scrambling identifiers (eg, or different sequences).

[0119]According to some aspects, TRP 105-A or TRP 105-B can indicate the Dragon 115-A to use the scrambling identifier to use for the PUCCH. In some embodiments, an indication of the scrambling identifier (e.g., by TRP 105-A or TRP 105-B) can dynamically signal in the DCI (eg, using the scramble identifier indicator in the DCI). Additionally or alternatively, the identifier can be configured for each PUCCH resource, and the UE 115-A can determine the scramble identifier based on the determined PUCCH resource.

[0120]In some cases, the path loss calculation can follow downlink reference signals with larger path loss. That is, if the PUCCH resource and two downlink reference signals (eg, the reference signal transmitted by different TRP) is QCL, the UE 115-A can calculate the path loss based on two downlink reference signal resources. There is a large path loss. For example, if the first down line reference signal has a path loss of 120 dB, and the second downstream reference signal has a path loss of 125 dB, the UE 115-A can determine whether the path loss is 125 dB. The UE 115-A can calculate the transmission power of the transmitted PUCCH message using the determined path loss (for example, compensation path loss). In one example, if the path loss is large, the UE 115-A can use a larger transmission power. If the PUCCH message is received (eg, correctly) at the two TRP 105, the UE 115-A compensates a larger path loss, so that the PUCCH message can be received by each of the TRP 105.

[0121]At least one of the TRP 105 can send a configuration message to configure the UE 115-A using the PDCCH monitoring set, and the configuration message can use the search space identifier and the control resource set identifier to indicate each PDCCH monitoring time. In the example, UE 115-a supporting multi trp can be configured with multiple control resource sets for each serving cell (active BWP) per time slot. In some examples, different control resource sets can have different QCL assumptions to illustrate the PDCCH sent from different TRP 105. In some cases, the PDCCH message can have the order based on different PDCCH monitoring timings. Therefore, the order in which the PDCCH message may be based on the identifier of the control resource set of the PDCCH message.

[0122]In the example, the PDCCH message from different TRP 105 can appear in different PDCCH monitoring timing, and different PDCCH monitoring timing can have the order. For example, if two PDCCH messages are received in the same time slot, one of the PDCCH messages may be "first" PDCCH message based on which of the control resource set, the PDCCH message, and the other PDCCH message can be " 2 "PDCCH message. The order in which the PDCCH message received in the same time slot may not be based on which PDCCH monitoring is received based on which PDCCH monitoring timing can receive a particular PDCCH message. For example, the "first" PDCCH message can be received in a symbol period that occurs later than "second" PDCCH message. In some cases, the UE 115-A, TRP 105-A and TRP 105-B can agreed that each serving cell number (eg, k PDCCH message) can be received as a UE capability per serving unit. Part, this can reduce the UE to implement complexity. For example, UE115-a can be configured to receive up to two PDCCH messages per space per serving.

[0123]Figure 3 andFigure 3B A corresponding example of the wireless communication system 300 and 301 that supports multi-TRP transmission in accordance with various aspects of the present disclosure is shown. In some examples, the wireless communication systems 300 and 301 can implement all aspects of wireless communication system 100 or 200.

[0124]The wireless communication system 300 can support the first transmission mode of the NCJT communication between the UEs 115-B, TRP 105-C and TRP 105-D. In the first transmit mode, TRP 105 can jointly send a PDCCH message and a PDSCH message (eg, mode 1: 1PDCCH + 1PDSCH). For example, TRP 105-C can send PDCCH messages 305-A to the UE 115-BTRP 105-C can transmit PDSCH messages 310-A ​​on the first spatial complex layer, and TRP 105-D can be multiplexed in the second space. PDSCH messages 310-a are sent on the layer.

[0125]The wireless communication system 301 can support the second transmission mode of the NCJT communication between the UEs 115-C, TRP 105-E and TRP 105-F. In the second transmission mode, TRP 105 can jointly transmit two PDCCH messages 305 and a PDSCH message 310 (eg, mode 2: 2PDCCH + 1PDSCH). For example, TRP 105-E can send PDCCH messages 305-B to the UE 115-C, and TRP 105-F can transmit PDCCH messages 305-c to the UE 115-C. The second transmission mode can include a PDCCH repetition. For example, PDCCH messages 305-B and PDCCH messages 305-c may be copies or copies of each other. Send PDCCH copies can make PDCCH more robust and improve the chance of at least one copy of the PDCCH message 305. In the second transmission mode, TRP 105-E or TRP 105-F can transmit a PDSCH message 310. In some cases, TRP 105-E can send PDSCH messages 310-B to UE 115-C. Or, in other examples, TRP 105-D can send PDSCH messages 310-c to UE 115-C.

[0126]In the first and second transmit modes, the PDCCH message 305 is repeated in the second transmission mode, which may indicate DAI / ARI / K1 for reporting ACK / NACK feedback. DAI / ARI / K1 can include in the DCI of the PDCCH message 305. A PDSCH message 310 can be transmitted per cc, and therefore, the number of ACK / NACK bit numbers used in the report feedback may be equal to the defined number of codewords scheduled by DCI ( For example, maximum), or the number of code characters in the PDSCH message 310. In some cases, the defined number of codewords per pDSCH scheduled can be indicated by an indicator (eg, information such as the information element such as MaxnrofCodewordssCheduleDBYDCI).

[0127]The UE 115 and TRP 105 can implement techniques to coordinate feedback for the UE 115 reporting PDSCH message 310 based on the transmission mode and the DCI included in the PDCCH message 305. In some cases, in order to improve reliability, TRP 105 can send two PUCCHs to the same ACK / NACK bit. For example, in the first transmit mode, the UE 115-B can send PUCCH messages 315-A to TRP 105-C, and send PUCCH messages 315-B to TRP 105-D, in some cases, PUCCH messages 315-A And PUCCH messages 315-B may include the same ACK / NACK bit. In the second transmission mode, the UE115-C can send PUCCH messages 315-C to TRP 105-E, and send PUCCH messages 315-D to TRP 105-F, Similarly, PUCCH messages 315-C, and PUCCH messages 315-D The same ACK / NACK bits can be included.

[0128]In the first example, the PDCCH message 305 can include a DCI comprising two ARI fields (eg, Ari fields 330-a and ari fields 330-b), which points to two PUCCH resources within the same time slot. Therefore, the UE 115-B can transmit PUCCH messages 315-A to TRP 105-C on the first PUCCH resource, and transmit PUCCH messages 315-B to TRP 105-D over the second PUCCH resource, which can be in the same time slot. Send a PUCCH message 315. Similarly, the UE 115-C can transmit the PUCCH messages 315-C to the TRP 105-E in the first PUCCH resource in the same time slot, and transmit PUCCH messages 315-D to TRP 105-F on the second PUCCH resource. In some cases, two PUCCH messages 315 can be transmitted within different TTIs (such as microeggam).

[0129]In a second example, by configuring, a PUCCH resource may include two resources having different QCL information (eg, time domain resources, frequency domain resources, code domain resources, or any combination thereof). For example, different QCL information can indicate different transmission / reception beam directions. In some cases, the first transmit / receive beam can point to the first TRP 105 (e.g., Trp 105-C, or TRP 105-E), and the second transmission / reception beam can point to the second TRP 105 (eg, TRP105, respectively. -D or TRP 105-F). The UE 115-C can transmit a PUCCH message 315 containing ACK / NACK feedback on both the time-frequency code domain resource. For example, the UE 115-C may transmit a PUCCH message 315 on the second time frequency code domain resource based on the first QCL association based on the first QCL association. In some cases, the DCI in the PDCCH message 305 can use a DAI and a K1 field to indicate the two time-frequency code resources.

[0130]In the third example, the ARI in the DCI can point to two separate PUCCH resources, where the UE 115 is to transmit a PUCCH message including a feedback message. For example, ari = k can point to PUCCH resources 2K and 2K + 1. In some cases, the RRC signaling can configure the UE 115 to have an ARI to two separate PUCCH resources.

[0131]In some cases, it can be scheder semi-seminated (e.g., via a semi-tension scheduling (SPS)) PDSCH message 310. For example, each downlink SPS configuration can send a PDSCH message per time slot. In some cases, a PDSCH message can be transmitted from different TRP 105, such as in implementing a wireless communication system 300 implementing the first transmit mode (eg, mode 1) or in implementing a second transmission mode (eg, mode 2). The TRP 105 shown in 301. In some examples under SPS configuration, TRP 105 can configure the UE 115 to send a PUCCH message 315 per PDSCH message 310.

[0132]In other examples under SPS configuration, TRP 105 can configure the UE 115 to transmit two PUCCH messages 315 per PDSCH message 310, where each PUCCH message 315 targets towards a TRP 105. For example, as a SPS PDSCH message (eg, PDSCH message 310-a or 310-b) feedback, UE 115-c can send PUCCH messages 315-c to TRP 105-E, and send PUCCH messages 315-D to TRP 105-f.

[0133]In the first example under SPS configuration, a PUCCH message 315 can be transmitted in the same time slot. For example, the PUCCH message 315 can be TDM in the slot. TRP 105 can configure two PUCCH resources in an SPS configuration. In some cases, the K1 value and the PUCCH resource can be transmitted in SPS-activated DCI.

[0134]In a second example under SPS configuration, a PUCCH message 315 can be transmitted in different time slots. TRP 105 can configure two PUCCH resources in an SPS configuration. The TRP 105 can also configure the time domain offset 325 (e.g., in units of time slots) for the second PUCCH resource of the first PUCCH resource. For example, as shown, the time domain offset 325 separates the PUCCH messages 315-C from the PUCCH message 315-D on the time domain. PUCCH messages 315-C and PUCCH messages 315-D can be sent in the same BWP 320. In some cases, the time domain offset 325 is referred to as ΔK. The SPS-activated DCI can communicate K1 for the first PUCCH message (e.g., the PUCCH message 315-C) signal, and the actual K1 value of the second PUCCH message (for example, the PUCCH message 315-D) may be K1. Offset 325 value (for example, δ)k+ K1).

[0135]Figure 4 An example of a wireless communication system 400 that supports multi-TRP transmission in accordance with various aspects of the present disclosure is shown. In some examples, the wireless communication system 400 can implement various aspects of the wireless communication systems 100, 200, 300 or 301 for communication between the UEs 115-D, TRP 105-G, and TRP 105-H.

[0136]In the third send mode, such asFigure 4 As shown in the TRP 105, the TRP 105 can jointly transmit two PDCCH messages 405 and two PDSCH messages 410 (eg, mode 3: 2PDCCH + 2PDSCH (same codeword)). The PDCCH message 405 can schedule the PDSCH message 410, and two PDSCH messages 410 (e.g., PDSCH messages 410-A and PDSCH messages 410-b) may include at least one codeword. Each codeword may correspond to a transmit block generated by the TRP 105 in the upper layer (e.g., MAC layer). For example, PDCCH messages 405-A can schedule PDSCH messages 410-A, and PDCCH messages 405-B can schedule PDSCH messages 410-B. The third transmission mode can be an example of a PDSCH repetition.

[0137]As shown, TRP 105-g can transmit PDCCH messages 405-A to the UE 115-D, and TRP 105-H can send PDCCH messages 405-B to the UE 115-D. In some examples, PDCCH messages 405-A and PDCCH messages 405-A and PDCCH messages 405-B can be transmitted to the UE 115-D in the same time slot. PDCCH messages 405 can schedule a corresponding PDSCH message 410 from the TRP 105. TRP 105-G can transmit PDSCH messages 410-A to UE 115-D, and TRP 105-H can send PDSCH messages 410-B to UE 115-D, where PDSCH message 410-A and PDSCH messages 410-B The same collection of at least one codeword. The PDSCH message 410 can also include the same set of at least one feedback process identifier (eg, having the same HARQ process identifier). Each of the set of at least one feedback process identifier corresponds to a codeword in at least one codeword. In some examples, the PDSCH message 410 can have different resource allocation, modulation coding scheme (MCS) configuration or redundant version, for example to accommodate different channel conditions between different TRP 105 and UE 115.

[0138]In the first example of the ACK / NACK feedback configuration in the third transmit mode, the PDCCH message 405-A and PDCCH messages 405-B may include the same K1 value and the same ARI. If the PDCCH message includes the same K1 and ARI parameters, the UE 115-D may send a PUCCH message 415. For example, the UE 115-D can send PUCCH messages 415-a to TRP 105-G or send PUCCH messages 415-B to TRP 105-H, or send the same PUCCH message to both TRP 105-G and TRP 105-H 415 . The number of ACK / NACK bits included in the PUCCH message 415 can be equal to the defined number of codewords disposed by DCI (eg, the number, maximum number). For example, the ACK / NACK bit number can be based on the number of codewords replicated in PDSCH messages 410-A and 410-B.

[0139]In a second example of the ACK / NACK feedback configuration in the third transmit mode, the PDCCH message 405 can include different K1 or different Ari. In a second example, the UE 115-D can transmit two PUCCH messages 415. Each PUCCH message 415 can follow K1 and ARI received in the corresponding DCI for PUCCH transmission.

[0140]Different or Ari based on K1, how the UE 115-D reports feedback can have differences. If K1 is the same but the ARI is different, the UE 115-D can implement PUCCH repetition. For example, PUCCH messages 415-A and to TRP 105-H of the TRP 105-G may be the same PUCCH message 415. If K1 is different, two different PUCCH messages 415 (e.g., having different ACK / NACK payloads) can be transmitted due to sprocket and ACK / NACK multiplexing and / or bundle across CC.

[0141]For example, UE 115-d multiplexing or may be determined corresponding to a plurality of bundled message 410 is PDSCH HARQ-ACK information bits for PUCCH transmission of a single message 415, and the determination may be based on two PDCCH messages 405 are the same as K1 Case. The multiplexing may refer to the feedback of the plurality of PDSCH messages 410 for transmitting in a single PUCCH message 415. For example, if the UE 115-d defines a first PDSCH 410-a of the NACK message and the second message 410-b of the PDSCH ACK, UE115-d may be 2-bit sequence indicating ACK and NACK (e.g., "01", wherein 0 Represents NACK, 1 means ACK) Send to TRP 105. Bundles can refer to the UE 115-D execute logic and operation on two HARQ-ACK information bits, and send 1 bit to one or more TRP 105. For example, if a first UE 115-d determined PDSCH information 410-a and the second NACK PDSCH information 410-b of the ACK, then the UE 115-d may be 1-bit NACK (e.g., (NACK) AND (ACK) = NACK Send to TRP105. The TRP 105 can provide a configuration message to configure the UE 115-D to perform multiplexing or bundle. The UE 115-D may determine execution multiplexing or bundle based on the configuration message received from the TRP 105 containing the information.

[0142], For any transmission mode described herein, if scheduling the PDSCH message 410 a PDCCH message 405 indicating that the corresponding HARQ-ACK bits to be transmitted in the same time slot, in some examples, the UE 115-d may correspond to The HARQ-ACK information bits of other PDSCH messages 410 received in another slot or component carrier are represented by the current HARQ-ACK information bit. For example, when used in combination with a multi-TRP, the techniques described herein can be applied to carrier aggregation.

[0143]In the third transmit mode (eg, mode 3), if the UE 115-D successfully decodes a PDSCH message 410-A, since each PDSCH message 410 includes the same codeword, the UE 115-D can skip the decoding another PDSCH messages 410-B (or vice versa). However, if two PDCCH messages 405 indicate different values ​​of K1 or ARI, the UE 115-D can still transmit two PUCCH messages 415.

[0144]Figure 5 An example of a radio communication system 500 that supports a multi-TRP transmission in accordance with various aspects of the present disclosure is shown. In some examples, the wireless communication system 500 can implement all aspects of wireless communication systems 100, 200, 300, 301, or 400.

[0145]The wireless communication system 500 can support the fourth transmission mode of the NCJT communication between the UE 115-E, TRP 105-I, and TRP 105-J. In the fourth transmission mode, the TRP 105 can collect two PDCCH messages 505 and two. PDSCH message 510 (eg, mode 4: 2PDCCH + 2PDSCH (different codeword)). PDCCH messages 505 can schedule PDSCH messages 510. For example, PDCCH messages 505-a can schedule PDSCH messages 510-A, and PDCCH messages 505-b can schedule PDSCH messages 510-b. In the fourth transmission mode, two PDSCH messages 510 (eg, PDSCH messages 510-A and PDSCH Messages 510-B) can include different codewords and HARQ process identifiers. Each codeword corresponds to a transmit block generated by the base station in the upper layer (eg, MAC layer), and a HARQ process identifier.

[0146]As shown, TRP 105-i may be 505-a PDCCH message is sent to the UE 115-e, and TRP 105-j may transmit the PDCCH message 505-b to the UE 115-e, TRP 105-i may be the message PDSCH 510-a transmits to the UE 115-e, and TRP 105-j may send a message 510-b PDSCH to the UE 115-e, in which the PDSCH message 510-a and 510-b PDSCH message carries different HARQ process identifiers Different codewords.

[0147]In the first example of the ACK / NACK feedback configuration in the fourth transmission mode, the PDCCH message 505-A and PDCCH messages 505-b may indicate the same K1 value. If the K1 value is the same, the UE 115-E can send a PUCCH message in which the ACK / NACK bit number corresponds to the total number of codewords disposed by both PDCCH messages 505-A and PDCCH messages 505-b. For example, UE 115-e can be PUCCH message 515-a to a TRP 105-i, or the UE 115-e may transmit the PUCCH message 515-b to the TRP 105-j, or the UE 115-e can be one PUCCH message 515 The TRP 105-I and TRP105-j are transmitted. In this first example, the UE 115-E can use DAI and ARI corresponding to the last PDCCH monitoring timing for PUCCH transmission and ACK / NACK multiplexing. The last PDCCH monitoring time can be based onfigure 2 The described control resource set identifier of the PDCCH monitoring timing. In some examples, in order to determine the timing of the last PDCCH monitoring, TRP 105-i is configured by the configuration message transmitted define the order in the received PDCCH monitoring timing and a time slot in a cell, wherein the PDCCH transmitted in the PDCCH monitoring time The message can be sent by different TRP 105.

[0148]UE 115-e can be the same whether the bundle or multiplex ACK / NACK feedback message based on the result PDCCH PDCCH message 505-a and 505-b of the gap feedback indicator (e.g., K1 or PDSCH to the HARQ timing indicator). For example, if the UE 115-e determines PDSCH message 510-a of the NACK and the PDSCH message 510-b of the ACK, the UE 115-e 105 may report the PUCCH message 515 to the TRP in a case where ACK-NACK multiplexing "NACK ACK "(for example, two bits). Additionally or alternatively, the UE 115-E can use the logic and operation of the HARQ feedback result in the case of ACK-NACK bundling and transmit a bit to the TRP 105. For example, if the PDSCH message 510-A is NACK and the PDSCH message 510-B is ACK, the UE 115-E will report NACK to the TRP 105 (for example, (NACK) = NACK). Based on the RRC configuration message received from the TRP 105 based on the UE 115-E, the UE determines that the ACK / NACK multiplexing should be executed or the ACK / NACK bundle should be performed.

[0149]In a second example of the ACK / NACK feedback configuration in the fourth transmission mode, the PDCCH message 505-A and PDCCH messages 505-b may indicate different K1 values. If the K1 value is different, the UE 115-E can transmit two PUCCH messages 515. For this second example, the number of ACK / NACK bits in each of the PUCCH messages 515 may be based on the number of codewords scheduled by the corresponding PDCCH message 505. Each PUCCH message 515 can follow DAI and ARI received in the corresponding PDCCH message 505 for transmission and ACK / NACK multiplexing.

[0150]In some cases, for the fourth transmission mode, TRP 105 may be configured by parameters corresponding to a maximum number of codeword DCI scheduling (e.g., maxNrofCodeWordsScheduledByDCI) is equal to "1", in order to reduce detection complexity UE. For example, if the UE 115-E detects a value having "1", the UE 115-E can determine that the wireless communication system 500 is operating in the fourth transmission mode. In some cases, each PDSCH message 510 can include a codeword. For example, if two PDSCH messages 510 are dispatched within one slot, each PDSCH message 510 may include a codeword or a DCI included in the PDCCH message 505 to schedule a codeword.

[0151]Figure 6 An example of a QCL association configuration 600 that supports a multi-TRP transmission in accordance with various aspects of the present disclosure is shown. In some examples, QCL association configuration 600 can implement all aspects of wireless communication systems 100, 200, 300, 301, 400 or 500.

[0152]The PUCCH resource can be configured to be associated with the downlink reference signal QCL based on the spatial domain parameter. For example, if configured, the UE 115-A can transmit a PUCCH message using the same spatial domain filter as the downlink reference signal associated with the corresponding QCL is configured. In some cases, the PUCCH resource can be configured to associate with a downlink reference signal QCL. QCL correlation can be based on parameters pucch-spatialreamfo. In some other examples, the PUCCH resource can have a different QCL assumption to two different downlink reference signal QCL, where each downlink reference signal is transmitted from a different TRP.

[0153]UE 115-f may follow PUCCH resource configuration QCL configuration and ARI to determine PUCCH message is sent to the TRP 105-k or TRP 105-l, or PUCCH whether the message is broadcast to the TRP 105-k and TRP 105-l two By. In some cases, the techniques described in the QCL association configuration 600 can be applied to the transmit scheme described herein.

[0154]In the first example, the PUCCH resource indicated by the ARI is associated with a downlink reference signal QCL, so the UE115-f can send a PUCCH message to a single TRP 105. E.g., PUCCH resource may be associated with a downlink reference signal transmitted in the beam 605 by the TRP 105-k QCL, or PUCCH resource may be associated with a downlink reference signal transmitted in the beam 610 by the TRP 105-l QCL. UE 115-f may send a message on the PUCCH corresponds to the beam and the beam 615,605 downlink reference signal from the TRP 105-k, or the UE 115-f and 610 may correspond to a downlink beam from at TRP105-l The PUCCH message is sent on the beam 620 of the reference signal.

[0155]In a second example, the PUCCH resource indicated by the ARI may have a different QCL assumption to associate with two different downlink reference signal QCL, so the UE 115-f can be inferred to send a PUCCH message to a plurality of TRPs. In a second example, the UE 115-F can transmit the PUCCH message simultaneously to two TRP 105. In this example, the path loss calculation can follow the downlink reference signal with a larger path loss. Based on the use of larger path loss, the UE 115-F can transmit the PUCCH using the transmit power relatively large than the transmission power of the smaller path loss, so that the PUCCH message can be properly received by each of the TRP.

[0156]In some cases, the UE 115-F can be configured having a plurality of scrambling identifiers (e.g., configured by an information element such as HoppingID), where each scrambling identifier corresponds to one of a plurality of TRP 105. The scrambling identifier can be used by the UE 115-F to generate a sequence (e.g., a low PAPR sequence, or a pseudo-random sequence) for the PUCCH transmission (eg, a PUCCH transmitted by Carrying ACK / NACK feedback). The generated sequence can be used as DMRS for PUCCH transmission (e.g., in format 1, 2, 3, and 4). Additionally or alternatively, the generated sequence can be used to modulate the payload of the PUCCH (e.g., in format 0). For the PUCCH transmitted from one or more UEs 115 to TRP 105-K and 105-L, interference between the UE 115 and TRP 105 can be reduced by different PUCCH scrambling identifiers (eg, or different sequences).

[0157]According to some aspects, TRP 105-K or TRP 105-L can indicate the Dragon 115-A to use the scramble identifier to use for PUCCH. In some embodiments, an indication of the scrambling identifier (e.g., by TRP 105-K or TRP 105-L) can dynamically signal in the DCI (eg, using the scramble identifier indicator in the DCI). Additionally or alternatively, the identifier can be configured for each PUCCH resource, and the UE 115-F can determine the scramble identifier based on the determined PUCCH resource.

[0158]Figure 7 An example of a process flow 700 for supporting a multi-TRP transmission in accordance with various aspects of the present disclosure is shown. In some examples, process flow 700 can implement all aspects of wireless communication systems 100, 200, 300, 301, 400, 500 or 600.

[0159]At 705, the UE 115-G can receive a configuration message transmitted by the TRP 105-M, which is configured to configure the UE to use a first coordinated transmission mode in different coordinated transmission mode and multiple TRP communication. For example, different coordinated transmission mode sets can includeFigure 3A ,Figure 3B ,Figure 4 withFigure 5 The first to fourth transmission modes described in it are described.

[0160]At 710, the UE 115-G may receive a DCI including at least one indicator from the TRP 105-M based on the configuration message. DCI can be sent in the PDCCH message. At least one indicator can include, for example, a DAI, a feedback resource indicator, a feedback gap indicator, or any combination thereof.

[0161]At 715, the UE 115-G can receive a first coordinated transmission of communication according to the first coordination transmission mode. In some cases, the first coordination transmission can be sent as a PDSCH message. In some cases, TRP 105-m in the TRP set of the first coordination message can be determined based on the coordinated transmission mode.

[0162]At 720, the UE 115-G may transmit a feedback message to the first coordinated transmission to at least one TRP 105-m in the TRP set according to a feedback configuration corresponding to at least one indicator and the first coordination transmission mode. For example, if the TRP 105-M is connected to another TRP 105 via an ideal return link, the UE 115-G can send the feedback message to another TRP 105 in some cases, and the other TRP 105 can be passed through an ideal The link communicates the feedback message to the TRP 105-M.
